A four-wing chaotic attractor and its circuit implementation.

Abstract

The Electro-chemical Society 247th ECS Meeting, Montreal, Canada, May 18-22 ,2025.By introducing a state feedback control to a proposed four-dimensional chaotic system, an extremely complex four-wing chaotic attractor is derived having larger positive Lyapunov Exponent (LE) than other chaotic systems. Spectral analysis shows that the system in the four-wing chaotic mode has very broad frequency bandwidth, verifying its random nature, and indicating the prospect for engineering applications such as secure communications. Finally, an analog circuit, implementing the new four-wing chaotic system, is presented
